The frigid and harsh homeworld of the Kryonians.

Very little liquid water exists on Kryonia unless you're willing to dig unreasonably deep through the frozen surface. Kryonians have little need to seek water, as the cold temperatures and any ambient moisture sustain them quite well.

Kryonia is a medium-large planet somewhat bigger than Earth.

Kryonia's surface is covered in a thick crust of ice and snow, into which the Kryonians have sculpted their civilization.

The climate of Kryonia is incredibly cold.

Kryonia is on the outer edge of the habitable zone of its host star, which contributes to the intensely cold climate enjoyed by its inhabitants.
